How can I make my SL400 air conditioner colder?

Park in the shade whenever you can, and use a reflective sunshade in the windshield when you’re parked. If you’re the only one in the car, close all the vents except the ones that point toward you. Give the system the final boost it needs with an A/C performance check and recharge from Firestone Complete Auto Care.

Why do I get hot air from my SL400 A/C?

If your car’s air conditioning isn’t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system.

How does my A/C system get a leak?

Over the years, the rubber seals and gaskets in your SL400’s A/C system naturally degrade. Moisture can get into the system and cause a malfunction, or parts can simply wear out so that your system no longer seals properly.

Does my SL400 A/C run on gas?

While your vehicle’s A/C system doesn’t directly use fuel, it does draw power from the engine, which can impact the fuel consumption of your SL400.

Why does the A/C in my SL400 smell like vinegar?

If the air conditioning in your SL400 smells like vinegar, it could be due to bacteria growth on system components such as the evaporator and heater cores. Bacteria can grow when moisture accumulates on air conditioning system components, providing a breeding ground for microorganisms.

What is causing my SL400’s A/C to only work when the car is in motion?

Damaged or worn components in your SL400’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.

A/C Repair Service for Your Mercedes-Benz SL400

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like lava. Your skin sticks to the driver’s seat. “Who can fix my Mercedes-Benz SL400 A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care — that’s who! We know Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 2016 Mercedes-Benz. Steer your Mercedes-Benz SL400 to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2016 Mercedes-Benz SL400 A/C system to evaluate what repairs are necessary (if any). We’ll test overall system performance, check for any leaks, and measure the system pressure. If any signs point to a possible leak, we’ll send a special U/V dye through the system, or use something called a “sniffer.” A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your Mercedes-Benz SL400 A/C system to detect refrigerant fumes escaping from the system. If there's a leak, we'll find it and fix it.

A/C Recharge for Mercedes-Benz SL400

While your 2016 Mercedes-Benz SL400’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. To start this process, a technician will flush out the old refrigerant from your vehicle’s A/C system. Next, they will evacuate the system according to Mercedes-Benz's recommendations. The A/C system is recharged with new refrigerant and once we’ve done a final test on the system ourselves, you're ready to get back on the road. We want you to be comfortable in your car, so we train our technicians to perform 2016 Mercedes-Benz SL400 A/C recharges.

Other Mercedes-Benz SL400 A/C Problems

Warm air isn't the only Mercedes-Benz SL400 A/C problem you may encounter. Another common A/C problem is weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. An A/C system that starts off blowing cold air but then turns warm may suggest a leak, a blown fuse, or a damaged compressor clutch. Are you breathing in some “interesting” new odors in your 2016 Mercedes-Benz SL400? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. We’re here to help you get back on the road in your SL400 — without all the sweat puddles!
